Weezer have finally made good on their promise to bring viral TikTok user Evan Marsalli onstage to perform ‘Buddy Holly’ with them.While performing in Madison, Wisconsin on June 14, Weezer closed out their set with the hit track ‘Buddy Holly’ featuring Diet Lite’s Evan Marsalli on guitar. The guest spot comes after a lengthy social media campaign that Marsalli ran on TikTok in an attempt to gain the band’s attention.Beginning in 2020, Marsalli posted a video of him playing ‘Buddy Holly’ onto TikTok every day for 990 days straight before Weezer’s Rivers Cuomo finally duetted with him.
